Silicon carbide eziko ityhubhuInamandla amakhulu, ubunzima obuphezulu, ukumelana nokunxiba kakuhle, ukumelana nobushushu obuphezulu, ukuxhathisa ubushushu, ukumelana nobushushu obulungileyo kunye nokuxhathisa ukothuka, ukuguquguquka okukhulu kwe-thermal, ukumelana ne-oxidation elungileyo kunye neminye imisebenzi egqwesileyo, isetyenziswa ikakhulu kwi-medium frequency cast, iziko lonyango lobushushu olwahlukeneyo, i-metallurgy. , imboni yeekhemikhali, i-non-ferrous metal exercise kunye neminye imisebenzi.

Iimpawu zeiityhubhu ze-silicon carbide eziko

Silicon carbide eziko ityhubhuyisilicon carbide njengeyona nto iphambili ekrwada, igqwesileyoiimveliso ze-silicon carbideeyenziwe ngokudubula kobushushu obuphezulu, kunye nokumelana nobushushu obuphezulu, ukuhanjiswa kwe-thermal ekhawulezayo, ukomelela okuphezulu, ubunzima obuphezulu, ukumelana nokunxiba okuhle, ukumelana nobushushu obulungileyo kunye nokumelana nokuzamazama komhlaba, ukuhanjiswa kakuhle kwe-thermal, ukumelana ne-oxidation elungileyo kunye neminye imisebenzi egqwesileyo kuzo zombini iziphelo zofakelo. isigqubuthelo esikhethekileyo sobushushu obuphezulu. Iyakwazi ukuphepha ngokufanelekileyo ukubola kwesisombululo sesinyithi kwizinto zokufudumeza zombane (kubandakanywa neentonga ze-silicon, iingcingo zokufudumeza zombane zombane, njl.), kunye nesicelo esiphambili se-silicon carbide iityhubhu zokukhusela ezinezibonakaliso ezahlukeneyo ezingcono kunezo zeemveliso ezahlukeneyo zegraphite zine-thermal conductivity, ukumelana ne-oxidation, ukuxhathisa ukothuka kobushushu, kunye nokumelana nobushushu obuphezulu

Itekhnoloji yokuvelisa ye-silicon carbide furnace tube

Imveliso yisilicon carbide njengeyona nto iphambili ekrwada, ngenkqubo ekhethekileyo yobushushu obuphezulu bokugcadwa kweemveliso ezigqwesileyo zesilicon carbide, umgangatho wobude unokwenziwa ngokwezifiso ngokweemfuno zabathengi.

Ukusetyenziswa kokuqala kweiityhubhu ze-silicon carbide eziko

Isetyenziswa ngokubanzi kuqeqesho lwentsimbi engeyombi, iimveliso ze-aluminiyam inkqubo yokukhupha amanzi, ukuprinta kunye noomatshini bokudaya, ukuqeqeshwa kwe-zinc kunye ne-aluminium kunye nokulungiswa kwemveliso kunye neminye imisebenzi.

Uphuhliso lwamashishini lwe-silicon carbide furnace tube

I-Silicon carbide furnace tube ineempawu ze-impedance ephezulu, ingxolo ephantsi, i-linearity enhle, njl njl. Ngenye yezixhobo ezikhawulezayo eziphuhliswayo ze-silicon carbide okwangoku, kwaye iye yathengiswa kuqala. Xa kuthelekiswa namacandelo e-MOSFET, amacandelo e-JFET awanazo iingxaki zokuthembeka ezibangelwa ziziphene zomaleko we-oksijini yesango kunye nokuthintelwa kokuhamba komthuthi ophantsi, kunye nokugcina amandla okusebenza ngamaza omoya aphezulu ngenxa yeempawu zokusebenza ze-unipolar. Ukongeza, izixhobo ze-JFET zinozinzo oluhle lokusebenza kunye nokuthembeka kumaqondo obushushu aphezulu. Ngenxa yobume besango le-electrode yesixhobo se-silicon carbide JFET, i-voltage yomgubasi we-JFET ihlala ingalunganga, oko kukuthi, kukho izixhobo eziqhelekileyo, ezingathandekiyo kakhulu ekusebenziseni kwayo kwinkalo yombane wamandla, kwaye ayihambelani nesekethe yangoku ye-universal drive. Ngokuzisa iteknoloji yesixhobo senaliti yegroove okanye isakhiwo segroove yemesa, isixhobo esomeleziweyo esinemo yokusebenza eqhelekileyo siyaphuhliswa. Nangona kunjalo, ekubeni izixhobo eziphuculweyo zenziwe ubukhulu becala ngexabiso leempawu ezithile zokumelana nesiphelo sangaphambili, kulula ukuphumeza uxinaniso lwamandla oluphezulu kunye nomthamo wangoku we-JFET engaguqukiyo (uhlobo lokuncipha), kunye nendlela yokudibanisa ukuncipha. uhlobo lwezixhobo ze-JFET kumxokelelwane ongaphezulu we-cascade luphunyezwa ngokudibanisa ii-MOSFET zeklasi ye-Si eziphantsi koluhlu. Isekethe yokuqhuba yesixhobo se-JFET se-cascade iyahambelana ngokwemvelo kunye nesekethe ye-drive yesixhobo se-silicon esinenjongo ngokubanzi. Ubume be-cascade bufaneleke kakhulu kumbane ophezulu kunye neemeko eziphezulu zokukhupha, kunokuba izixhobo ze-silicon ze-IGBT zendabuko, ziphephe ngokuthe ngqo ingxaki yokuhambelana kwesekethe yokuqhuba.

Izibonelelo ze-silicon carbide zimi ngolu hlobo lulandelayo.

I-1, umsebenzi wokudlulisa ubushushu ulungile, udonga lwetyhubhu luncinci (iimilimitha ezimbalwa kuphela), impendulo yokutshintsha ubushushu bemveliso ishushu kakhulu;

2, ayichatshazelwa kukuhlwa

I-3, ubushushu obuphezulu abunyibiliki, ulwelo lwesinyithi lungcoliseka;

I-4, ingasetyenziselwa ukunyibilikisa i-sodium kunye ne-strontium rich alloy;

I-5, ukubonakala kwemveliso akuqhotyoshelwanga kwi-slag, ukukhuselwa kulula kakhulu;

6, ukumelana nobushushu obuphezulu 1600;

7. Ukuxhathisa ukothuka kwe-thermal

I-8, ubunzima obuphezulu, akukho lula ukwaphula

9 Ukonga imali, ubomi ngaphezu kwesiqingatha sonyaka.

Oku ngasentla ziimpawu zokusebenza ze-silicon carbide furnace tube, ukuba ufuna ukwazi ngakumbi, unokuziva ukhululekile ukuqhagamshelana nathi!
